Overview

Store 2FA codes in an encrypted vault. Generate TOTP/HOTP locally and sync with the 2FAU desktop app for macOS, Windows and Linux.

2FAu is a fast, local-first authenticator for your two-factor (TOTP/HOTP) codes. Your accounts live in an encrypted vault right in your browser — there is no account to create and no server to breach, and your secrets never leave your device. Features • Encrypted vault (AES-256-GCM) unlocked by a single passphrase • Popup with colour-tinted rows and search-as-you-type • Hotkeys: open the vault (Ctrl/Cmd+Shift+U), copy a code (Ctrl/Cmd+1–5), autofill the focused field (Ctrl/Cmd+Shift+Y) • Enroll by scanning a QR straight off the current tab — no phone needed • Sync as encrypted chunks through your browser profile, or point it at your own 2FAu desktop app over loopback • Same Rust crypto core as the 2FAu desktop app for macOS, Windows and Linux • Open source (MIT) 2FAu never sends your codes or secrets anywhere. No tracking, no analytics, no data collection.
